line (1,3),(-1,-1)

Solution

line

(1, 3), (- 1, - 1)

Solution

y = 2 x + 1

Solution steps

Find the line

y = mx + b

passing through

(1, 3)

,

(- 1, - 1)

Compute the slope

(1, 3), (- 1, - 1) : m = 2

Compute the

y

intercept:

b = 1

Construct the line equation

y = mx + b

where

m = 2

and

b = 1

y = 2 x + 1
